application filed October 20, 1910. Serial No. 588,082.

To all whom). i may concern:

Be it known that I, Halnnv CHALUPA, a. citizen of the United Stiit'es, residing at Iowa City, in the county of Johnson and State of Iowa, have invented a new and useful Mechanical Movement, of which the t'ol lowing is a specification.

This invention relates particularly to a mechanical movement to be attached to wind -111illS, particularly that class in which a crank receives its motion from a main shaft directly secured to theblades of the mill.

.The particular objects of this invention are to provide a mechanical movement that will eliminate greatly the back lash or lost motion between the parts, particularly when the crank of the mill passes over the center at the top, when the weight of the rod and its connections tend to cause the crank to turn suddenly ahead and thereby cause a severe pounding and hammering of. the parts during each stroke. The result of this pounding and hammering of the parts during each stroke, causes rapid wear and dis-- organization of the parts. This invention overcomes this difficulty and gives a more even action to' the crank throughout its whole turning motion as will become apparent 5's it is more fully set forth.

Another object of this invention is to have the parts so arranged and designed that they will he inexpensive to manufacture and can be easily installed, and can be readily inspected and repaired at any time, when necessary.

Other objects of this invention will become more apparent as it is more fully set forth.

In the accompanying drawings which illustrate by way of example an embodiment of this invention; Figure 1 represents aWiew in elevation of a mechanical movement embodyin this invention; Fig. 2 is a side view of Fig. 1; Figs. 3 and l are diagrammatic views indicating the various parts of the mechanical movement in various positions.

Similar reference characters refer to similar parts throughout the drawings.

In the construction which illustrates this invention 1. represents the uain frame Work or base or tower which supports the stand 2 arranged to hold the wind mill proper, and also to permit the pump rod 3 to reciprocate therein, in the well. known manner. This stand 2 is suitably mounted on the tower 1, so that it can be easily revolved to turn to meet the wind as is usual with this class of apparatus.

Provided on the upper portion of the tower is a bearing plate -1- ar 'anged to take the wear, and weight of the stand 2, as is clearly shown in the drawings.

Thestand 2 is provided with an arm 5 integrally secured to one side of it and projecting upwardly. The upper portion of this arm being drilled to receive a shaft 6 on which oscillates a pair of pitman rods 7 and 8. A pitman rod 7 is arranged so that its end portion 9 will engage with the upper portion of the pump rod 3 and suitably guide it as it reciprocates in the manner more fully described in the latter part of the specification, the portion 9 of the pitman rod 7 is also arranged to receive an intermediate rod 10 that is pivotally secured to a link part 'lLthat has one of its end portions disposed on, and secured to a crank 12 that is actuated by a blade shaft 13 of the wind mill. The lower part or opposite end of the link 11 is arranged to pivotally receive the remaining end portion of the pitman rod 8, which is suitably bent to be inserted therein.

14 are suitable screws arranged to adjust the various parts on which they are dis posed, so that the action of all of the parts can be made as etlicientpossible.

In ope ation the wind mill shaft l3, that is actuated by blades of the same, and in turn causes the crank to rotate thereon, at

the same time, will move the link part 11 in:

a path, the direction of which will be greatly controlled by the rods 8 and 10 and incidentally by 7 and 3, as ran be readily seen in the diagrannnatic views 3 and 4.

'It will be noticed that the crank shaft is disposed slightly off center to that of the shaft 3, in order that there will be no dead centers when the device is working, at the same time, the movements of the rod 10 will be more positive, being situated more directly under the rod 7 than would be the case if it was directly attached to the crank 12 at its end portion.

By having the pitnian rod 8 secured to the lower end of the link part 11, means are provided whereby a great part of the strain, that would naturally come on the crank 12, is greatly eliminated thereby preventing it from being damaged as is usually the case after but a little use. It will also be noticed by referring to the diagrams that the motion is so taken up by the various rods 7, 8, and 10 and the link 11 that the pressure exerted on the pump rod 3 is practically uniform throughout the entire movement of the crank, Which'greatly adds to the efli ciency of the device as Well as the Wear of it.

Vhile the general operation of this mechanical movement produces a uniform action on the pump rod, at the same time, it serves to take up a part of the weight on the rod itself, and so distribute it that an even strain will be exerted on the various rods, but as little as possible on the crank that actuates it.

By adjusting the nut 14 above the crank rod 3 one can readily take up any Wear that may be produced in the same, under the usual circumstances. By adjusting the other screws the Wear in the other parts can also be taken care of so that the device in general can be kept in perfect Working condition.

Any suitable means for oiling can be attached to this mechanical movement, as it is not desired to restrict that portion of this device in any Way.

Obviously While there is shown but one construction of this invention it is not de sired to limit this application for a patent in any Way, otherwise than necessitated by the prior art, as many modifications in the construction of this invention may be made Without departing from the principles thereof.

Having thus described this invention it is claimed:

A mechanical movement comprising in combination a body proper, said body having an arm projecting SlClGWiSG and upwardly and provided with a hole therethrougli, a shaft disposed in said hole, a plurality of rods pivotally mounted on the said shaft, a crank shaft rotatably disposed in said body, a crank disposed on the last mentioned shaft, a link pivotally secured to said crank, an intermediate rod connecting rnc of said rods to the central portion of said link, another of the first mentioned rods ivotally secured to the end portion of said link. and a pump rod or the like sooured to the rod and intermediate rod, which are connected together, so that the motion transmitted from said crank shaft will cause said pump red to 1'cri1n-orate in a quasi uniform manner.
